Paper Abstract

We here study the transmission performance of differential phase-shift keying (DPSK) modulation compared to the traditional On-Off keying (OOK) modulation in the potential high speed satellite to ground laser communication applications. By modeling the channel from the satellite to ground using widely accepted theoretical model and measured results, we estimate the scintillation-induced received power fluctuation. Through simulations, we show that DPSK systems using direct detection with balanced receivers has a clear advantages in performance over the OOK, especially under significant scintillation in the atmosphere.
